Sequential batch reactor (SBR) process is basically a fill-and-draw activated sludge process. Being a very popular technology, SBR was not being frequently used for the treatment of wastewater like activated sludge process (ASP). This paper reviews two case studies, where SBR was used for capacity expansion of existing and ASP was converted to SBR.
Studies on the removal of zinc by adsorption on two types of flyashes, namely Bokaro Thermal Power Plant Fly ash and Fluidized Bed Combustion Fly Ash from Tata Steel, Jamadoba were carried out.
Dairy industry generate large amount of white highly turbid liquid waste products which cannot be processed further in the industry and has to be discarded. They contain very high organic matter that may be in dissolved or colloidal form and is thus very high in BOD and total solids.
The present study deals with physico-chemical analysis, treatment and utilization of Deoband sugar mill effluent. The effluent is treated with alkaline solution of hexacyanoferrate (III). 2007
A three phase inverse fluidized bed reactor was used to treat the starch industry wastewater. Experiments were carried out at different initial substrate concentrations and for various hydraulic retention time. (2007)
The physico-chemical profile of effluent from sugar mill was determined during 2003-04. The parameters measured are temperature, colour, turbidity, pH, electrical conductivity, BOD, COD, total dissolved solids, chloride, total alkalinity, total hardness, sulphate, phosphate, total acidity, calcium and magnesium.
Tonnes of deadly toxic waste, which killed 10 people and made thousands ill in Ivory Coast were recently shipped out of the country in sealed containers, bound for a treatment plant in France.
Unwise dumping of wastes in land lead to soil followed by water pollution. Wazirpur, an authorized industrial area, in Delhi, is one of the major sources of pollution in this city.
The laboratory model of Rotating Biological Contractors (RBC) which was used in the present study, is a modified one, in respect of, increased reactor depth, varying depth of submergence of rotating discs and supplemental air supply. Synthetic sago wastewater was used to study the performance of the modified RBC.
